View Object / setWhereClauseParameters()

Hi,
I am using BC4J in a servlet to access a database. I have a view that uses "?" style parameters. I am successfully setting the parameters and executing the query. My problem occurs the second time I set the parameters and execute the query. Here is a synopsis...
setWhereClauseParameter(0, "asdf");
setWhereClauseParameter(1, "0");
executeQuery();
I get the expected results, i.e., it returns the row I expect. Lets call this row "asdf"-"0".
now...
setWhereClauseParameter(0, "asdf");
setWhereClauseParameter(1, "1");
executeQuery();
I get an unexpected result here. What I get is the same as the first query, i.e., "asdf"-"0". I expect "asdf"-"1".
The only way I can get the expected results on the seconde query is to do a a commit after the first query.
Here is my question...Can someone please explain to me why this is happening and hopefully steer me in the direction where I don't have to do the commit after the first call?
Thanks in advance,
Kirby

Questions on ADF View Objects, Links and Iterators

I have a number of questions regarding using ViewObjects in applications where there are alot of relationships between tables.
First, lets say that I have ViewObject SomeView that was added to the App Module (AM) as VO1. And because it has a number of "detail" records that have to be iterated through in a "report like" view it has those other VO's added under it as "children" in the AM.
So I have
VO1 (an instance of SomeView)
--> VO2 (an instance of some other view)
--> VO3 (an instance of some other view)
that is used on pages where only a single VO1 is shown at a time.
Now because I had another page I wanted to make that had a listing of all SomeView objects. Some of the fields in SomeView are foreign keys to records in VO2 and VO3 and while I don't want to show all the fields from VO2 and VO3, I do want to show a name field from each rather than just the foreign key.
My experience (though I've never read this anywhere) tells me that when doing a "table" that is a list of rows from a VO, you can't display info from the child VO's because the child VO's are on whatever record corresponds to the "currentRow" in the parent VO and just displaying the rows in a rangeSet doesn't make each the "currentRow" so even we display 10 records in a for loop, the "currentRow" is just one, and the child VO's iterators aren't moved as we go through the for loop. (Can someone confirm if I am correct on this conclusion????)
So the only way I know of to show some field from a related table in each row is to make the VO have the entity objects from the related tables be part of the view as references. Is this the only way?
If I do that on a view that didn't have other views as children defined in the AM I don't have any problem and it works like I want.
But if I do it on a view that did have other views as children defined in the AM it makes the page(s) using that view with the children iterators behave badly. Half the information quits showing up, etc.
For example, ... if I go to the "SomeView" which was defined with only one entity object association, and I add the entity objects (that are the basis of instances of VO2 and VO3 ) as referenceable only, it totally breaks the page where I display a single VO1 and use it's VO2 and VO3 children. IS THIS NORMAL OR AM I MISSING SOMETHING?
So, is the solution that I have to have more view objects defined for different purposes ?
Can anyone give any general guidelines for when/where to use different view objects vs. when to use different iterators. I'm not having much luck with using secondary RSI's and haven't found much info on them.
Also, how about issues of naming iterators that are in various binding containers (ie. UI Model for a page). If I do and LOV it creates an iterator and gives it a default name like ViewNameIterator1. If I already have a different page that uses a regular (non LOV) iterator with that name, and the user goes back and forth between those pages, is that a clash?
Finally, I've read a couple of Steve Muench's blogs on View Link consistency but I'm not sure what the rules are on when it applies and doesn't. How you turn it on or off, etc. One of his examples in http://radio.weblogs.com/0118231/2004/02/27.html talks about it in the context of two view objects that are NOT typically "linked" in a master/detail kind of way. Like an AllDepartments and a DepartmentsLessThan view. Do you have to create a View Link between them to have results of one be reflected in the other if they aren't used in the same page in a web app? Or does it happen automatically (with the caveat that you have to do the rowQualifies method). Just feels like I'm missing some pieces.
Thanks in advance,
Lynn

Hi,
I am also interested in a best-practice note from oracle.
Currently we store history in seperate history tables for columns that changed. All this implemented in our BaseEoImpl overriding the EntityImpl.prepareForDML().

A dynamic View object at runtime

Say there is an inputtext component and one LOV. User will enter a number, say 7, and then press a Submit button. And then in the LOV, user will be able to see the numbers from 1 to 7.
Is it possible to achieve the same?

Hi,
am not sure what exactly you are trying to achieve here,
but from your description, it looks like a query dependency to me..
So in your VO that will be used as the List of Values for the attribute you want, create a View Criteria that meets the requirement you want (seems like 'Less than or Equal To' is what you need).
So eventually, you will end up with a ViewCriteria and one bindVarialble in that LOV View Object.
Since you havent described your BC model, I can only assume that you have one main VO and both UI component are binded to attributes of that VO.
Now go back to your main VO and update the LOV View AcCessor to use the ViewCriteria specifying the proper value on the Bind Variable.
Hope this helps,
Regards,
Dimitrios.

View Object to read data from a java file

Hi,
I am using JDeveloper 11.1.1.4 and ADF-BC in my application.
For one of my view objects , I want the data to be read from a java file which exposes some method to return a collection.
I cannot use a static view object in this case.
Please suggest the best way to implement this requirement.Basically build a view object that should read data from a java file.
Thanks,
Praveen

Depending on your use case you can either use a programmatic VO or directly expose the JV class as a data control.

Refreshing the screen using a View Object

Hi Experts,
Here is my requirement.
I have a View Object which queries the database and displays the results.
So I want to my VO to be executed when I click on Refresh button.
How can I achieve this?
Is there any example for this?
Thanks in advance

I think the mistake u did is populating the collection/entity of your custom view in some other place rather than on_new_focus method of the context class. So when u first time come to the view, it is calling your custom code and populating your custom view. But when u click new, it is not executing that method and it is not refreshing. on_new_focus is called everytime
you change to new or open in edit mode..that method should be declared as event handler method..
Move your code to the on_new_focus method of the particular context node. see standard codes how that is created and used...
e.g. you can see the component/view BT112H_SC/Details, context node BTPARTNERSET and method CREATE_BTPARTNERSET of CL_BT112H_S_DETAILS_CTXT of how it is used.

Error in Creation of a New View Object from Existing Entites

I define a Complex JOIN in the expert mode of the View Object Creation Mode. On trying to access the VO, the system returns an error, unable to creat View Objecy.
THe SQL Statement begins with
SELECT * from ( select ...My actual Query)
Is it possible to define ur own view objects with the same flexibility as the Data Tables

Hi Saket,
Following will be required for created a custom business object.
1. Object Type - ZTEST (Internal Techincal Key)
2. Object Name - ZTESTNAME (Technical Key Name)
3. Name - TEST (Name of BO, it is used while selecting the object type)
4. Description - (Short Description of BO)
5. Program - ZTESTPROGRAM (ABAP program in which the methods of the object type are implemented)
6. Application - A or B.. etc (Area to which your BO is related)
Please remember that you can learn these basic things by giving F1 help on those fields and in HELP.SAP.COM.

OAF Export button fetching data in one column - view object using union all

Dear All,
Export button showing data in one column from view object,
View object is based on mulitple queries with union all ,
Please let me know the solution for this issue.
Thanks
Maheswara Raju

Maheswara Raju,
As per my understanding you are not able to export all the View Attribute using export Button. Only the attribute which is used with the item/region will get exported.
There are few work around in case if you want to export the column without showing on OAF Page. Let me know.

Maintaining data of view objects in cache memory for repeated usage

Hi,
     We are developing an application which is having around 800 viewobjects that will be used as LOV in different screens. Therefore, it is decided to create a separate project for all such LOV view objects and keep the same in shared scope so that the data can be made availabe across the application.
     The application also communicates with different database schemas based on the logged-in county. For a particular user, LOV view object LovView1 should get the data fetched from Schema1 whereas for user2, the same LovView1 should get the data from Schema2.
     For this, we have created n number of ApplicationModules like AM1, AM2 etc in the project each one being connected to different database. A base application module also has been created and all the county specific AMs extend this base AM. Also all the LOV view object instances are included in this base AM so that they will be available in the county specific AMs also.The entire project is made as an ADF Library jar and this base AM is utilized by other projects for mapping the LOV by attaching the library.
     At runtime, whenever a particular viewobject is accessed, the findViewObject() method of the baseAM has been overridden and the logic is built in such a way to get the logged in user's county code from a session variable and based on the county, the corresponding AM is communicated with and the view object is returned.
     The view objects of the LOV project is used as LOV as well as for doing some other backend processes. In such cases, the view object is obtained and necessary filter conditions are appended to the view criteria and is executed to get the filtered rowset.
Now, my questions are,
1. Is it enough to create the jar for the LOVProject and access the view objects from the same baseAM across the application?
2. I wish to keep all the data in cache memory to avoid repeated DB hits for all the LOV view objects. How it can be achieved? To be more precise, consider two users user1 and user2 logging into the application with different county. When user1 access a LOV viewobject for the first time, data needs to be fetched from the DB, kept in application scoped cache memory and return the rowset. On subsequent calls to the viewobject, the data needs to be retreived from the cache and not from the DB. When user2 also access the same LOV viewobject, the same logic as explained for user1 should happen. How can I achieve this? Actually my doubt is when user2 access, will the data pertaining to user1 remains available in cache? If not, how to make it retain the data in cache?
3. I also wish to append a particular where condition to a viewobject irrespective of other considerations like logged in county, existing view criteria etc.. How can I do this? A separate thread for this requirement has been posted in the forum Including additional where clause conditions to view criteria dynamically
Kindly give me your suggessions.
Thanks in advance.
Regards.

Hi Vijay,
regarding your questions:
1. What is the difference between "TimesTen In-Memory Database" and
"In-Memory Database Cache" in terms of features and licensing model?
==> Product has just been renamed and integrated better with the Oracle database - Times-Ten == In-Memory-Cache-Database
2. Is "In-Memory Database Cache" option integrated with Oracle 10g
installable or a separate installable (i.e. TimesTen installable with only
cache feature)?
==> Seperate Installation
3. Is "In-Memory Database Cache" option same as that of "TimesTen Cache
Connect to Oracle" option in TimesTen In-Memory Database?
==> Please have a look here: http://www.oracle.com/technology/products/timesten/quickstart/cc_qs_index.html
This explains the differences.
4. After integrating "In-Memory Database Cache" option with Oracle 10g, data
access will happen only through Oracle sqlplus or OCI calls. Am I right here
in making this statement?
==> Please see above mentioned papers
5. Is it possible to cache the result set of a join query in "In-Memory
Database Cache"?
==> Again ... ;-)
Kind regards

How to add a new table or view in the view object

hello,every one.
I wanna add a new table or view in the view object's query statement.
when the table or view not in the where clause,the query statement is working fine.
If they in the where clause,I got the "java.lang.NullPointerException".
who can help me
thank you very much

thank you for your reply
I wanna extend the VO
oracle.apps.pay.selfservice.payslip.US.server.PayPayslipGetPersonDetail
the original sql is:
SELECT ppf.person_id,
FROM per_people_f ppf,
per_assignments_f paf,
pay_assignment_actions paa
where paa.assignment_action_id = :1 AND paf.assignment_id = paa.assignment_id AND SYSDATE BETWEEN paf.effective_start_date AND paf.effective_end_date AND paf.person_id = ppf.person_id
I wanna extend:
SELECT ppf.person_id, pay_v.element_name,pay_v.assignment_action_id
FROM per_people_f ppf,
per_assignments_f paf,
pay_assignment_actions paa,

pay_v.assignment_action_id =paa.assignment_action_id
if the pay.v in the where clause. I will got the exception. whereas,it's works fine.

Decode statement in Select line of a View Object Query

I attempted to create a view object in expert mode with a customized query.
The query had a decode statement in the select line of the query. The view
object compiled correctly but gave an error when run.
ex: select .... decode(CrpSchools.SCHOOLS_ID,null,CrpCustSchools.SCHOOL_NAME,CrpSchools.SCHOOL_NAME) SCHOOL_VALUE, ...
from ....
where ....
The error was that school_value does not exist in the statement. I got the error when
doing a vo.executeQuery().
When I removed the decode statement everything worked correctly. Does anyone know if
the decode statement cannont be used in the select line of a query in a view object?
Or maybe I was linking the query column (SCHOOLS_ID) up to the view attribute (SCHOOL_VALUE) incorrectly in the
Attribute Mappings tab of the VO wizard?

There should be no problem using a DECODE() statement, provided that you've aliases the column as you have done.
At design time, if you click on the (Test) button, does your query test ok?
Are you by chance applying a custom where clause at runtime?
If so, are you saying:
setWhereClause("yourtable.column_alias = ?";
or are you doing:
setWhereClause("column_alias = ?";
for an expert-mode query, you'll need to use the latter syntax.

ADF table and ADF form on the same view object

Hi,
As per the ADF demos available on ADF site, I created a jsf page with 2 panels. One panel is an ADF table based on a view object. And the other panel is and ADF form based on the same view object. My requirement is that as I scroll through the records in the ADF table, the ADF Form should dynamically display the details of the record in the ADF table. My understanding is that this should be automatic. However, its not working as expected. What have I missed?

Hi,
Apply PPR for form that displays details.
Like :
<af:table id="t3">
</af:table>
<af:panelFormLayout id="pfl2" partialTriggers="t3">
</af:panelFormLayout >

Issues in persisting dynamic entity and view objects using MDS

Hi Frank,
I m trying to save entity and view object xml by calling writeXMLContents() and saveXMLContents() so that these objects can be retrieved using the xmls later on.
These methods internally use MDS configuration in adf-config.xml, which is creating the issue.
Please share your thoughts on resolving this or if, there is any other way of creating dynamic entity/view objects for db tables created at runtime.

Problem while Binding multiple Parameters to View Object[Solved]

Hello,
I am facing problem while binding multiple parameters with different data types in View Object query. For example suppose I have following query in my view object.
SELECT Header.ADDED_BY
Header.BATCH_ID,
FROM BATCH_HEADER Header
WHERE :1='deptAdmin' and Header.BATCH_ID
in
select batch_id from batch_header_dept_mapping where dept_id in(SELECT * FROM TABLE(CAST(:0 AS TABLE_OF_VARCHAR)))
I am able to pass the Bind variables of Array type for : 0 , using Steve's ArrayOfStringDomain example. (ArrayOfStringDomain) .
But after passing value to second bind parameter ie.. :1 .
I am getting the error as follows.
## Detail 0 ##
java.sql.SQLSyntaxErrorException: ORA-00932: inconsistent datatypes: expected - got CHAR.
I tried to set
setWhereClauseParam(1,11); // 11 is Number
setWhereClauseParam(0,arr); // arr is arr = new Array(descriptor,conn,deptid); for in parameter.
But of no use , Please let me know if any thing missing form me or have any another solutions. Also please provide me any example if have.
Thank you,
Sandeep

hi.
but when using non-Oracle named parameter binding styles as you've done (ie. , :1), regardless of what number you give each bind variable, they are sequenced 0, 1, 2 etc. As such your bind variable :1 is the 0th parameter, and your bind variable is the 1st parameter.Your statment is correct.
:1 i used was actually on 0th position and :0 was on 1 position. Like you said in sequence 0,1,2 etc. Now i get the answer and i corrected My mistake by assigning right values to right binding variable. and problem just solve.
Thanks Chris.

Filter view object by selected values from list of values

Hello,
I've the following problem with my ADF Application. I have three view objects in my application module. Two of them are connected via a view link. For example take users, who are connected to their departments. The remaining view object consists of factories. Now I want to show the user/department dependency in a tree table and the available factories in a list of values. This list of values should be used to filter the shown users.
I've already tried to use bind variables in the users view object. But I don't know how to fill them with the value of the list of values.
Can someboy give me a tip how to solve this problem.
Best regards,
Enno

Hi Enno,
Try this:
- Have a AM method with one parameter(which takes user from the list of values) and inside AM method write code to set the bind parameter value and execute the query
Sample Code
public void filterByUser(String user){
   //Get your UserViewObject instance to userVO
   userVO.setNamedWhereClauseParam("<Bind_Variable_Name>", user);
   userVO.executeQuery();
}- Expose the method as client interface
- Drop the method (Data Control) as a button on to the page and pass the listofvalues value as a value to the method binding param
Something like this: ${bindings.<User>.inputValue}
- Finally refresh the master and detail tables based on the ListOfValues selection by setting partialTriggers property to the listofvalues component id
Hope it is clear

Cannot select different values from a table in a view object

Hi everyone,
I have two tables, Employee : ID, NAME, SALARY, NO_ROLE and role : ROLE_ID, ROLE_EMP. I join them with NO_ROLE and ROLE_ID. I created a view object with these two tables in JDeveloper, I made a LOV with ROLE_EMP and I want to be ale to create an employee with his ID, NAME, SALARY and by choosing a value in the ROLE_EMP list. The problem is that when I choose a ROLE_EMP, I cannot commit because the link between ROLE_EMP and ROLE_ID is not made correctly in ADF.
In SQL, that's what I'm trying to do: INSERT INTO Employee VALUES (ID, NAME, SALARY, NO_ROLE) WHERE NO_ROLE = ROLE_ID of the ROLE_EMP I have selected.
Thanks for your help ;)
PS: I followed this tutorial to do this, but it is not exactly what I want to do: http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_55/jdtut_11r2_55_2.html

To be more generic, when I create an employee and select his role_emp (the name of the role) I want that the role_id of the role_emp to commit.
